Any objection to renaming this bug title to something more accurate such

I have successfully created a kvm based reproducer.
1) get an image
$ wget
https://cdimage.ubuntu.com/ubuntu-server/daily-live/pending/noble-live-server-amd64.iso
2) Create bcache disk
$ fallocate -l 20G image.img
$ make-bcache -C image.img
3) Boot into iso with multipathed bcache disk
$ kvm
Fundamentally my setup is different than the scenario set up in the bug.
I was initially confused why multipathing was even happening, so I will
explain the scenario here. In case someone else is also confused.
The hardware is a JBOD enclosure where each disk has redundant I/O,
hence the
I attempted to reproduce this issue in a VM and wasn't succesful. I
essentially copied the tgtbasedmpaths test but made the backing disk
bcache cache before setting up the targets.
1) create vm
$ lxc launch ubuntu-daily:noble --vm n-vm
$ lxc shell n-vm
# apt install -y lsscsi multipath-tools

We have been chasing such a setup for a while (Sergio and I), but didn't
manage to get it working. Do you have a simple recipe for such a setup,
Christian?
